As a parent, step parent and granny, I think that you can only do your best, hopefully showing your children some good ideas of how to live in harmony, when they look at you and your husbands ways of living. Absolutely you can be the onlooker and see how something is not going to end up well, but there is not usually a safe way to speak about this,and all you can do is be there, when and if it goes pearshape. My son would have been very unlikely to accept any direct comments on women he went out with etc, but whilst at times I was in despair about his relationships, he still seemed to see me as a reasonably intelligent person, because when it came to changing jobs or thinking of a big commitment to something, he would ask me for my views. Didnt mean to say that he necessarily followed my advice, but he did recognise that having lived longer and travelled a fair bit, I might have some ideas that he had not considered. There have been 2 things he asked advice about and then ignored my suggestions and admitted that he was sorry he hadnt listened later, which I had had to bite my lip not to make any further comment at the time, but felt quite pleased that he considers my two pennorth worth listening to. But , he is a man, with his own family now and whatever he does or does not do is down to him and his own ability to look around situations and not be overcome by something so that he does not consider all the points. We did the best we were able to, as parents, as I am sure most of us did. If they go against things that are important to us or make choices that we dont really like, we need to think that we have done our job by bringing them up to make their own decisions, stand by them, good or bad and certainly not blame us for what happens next!! The big effort is accepting that it is not our responsibility to make decisions for them any more as they grow up and get jobs etc. Unless they are still living with you, and you may have house rules such as no smoking or whatever, but these rules would pertain to anyone living there, not just your children. Everyone has good and bad points, and I think if they have managed to arrive at adulthood with very little serious problems you have done a good job.
